7.3 AC current range
The measured value is obtained and displayed as real r.m.s. value (True RMS,
AC coupling). Its calibration is adapted to sinusoidal curves. In case of devia-
tions from this curve shape, the accuracy of the displayed value decreases.
Crest factor < 2.0 up to 100 % of each final measuring range value
Crest factor < 4.0 up to 50 % of each final measuring range value
